According to the calculation of the prevalence rate, the chronic obstructive pulmonary disease in China exceeds 1 hundred million patients.

The existing treatment modes of chronic obstructive pulmonary disease mainly comprise oral administration, injection, inhalation and the like, but the oral administration and the injection firstly send the medicine to blood and then to the lung, so that the medicine treatment efficiency is lower. With the development of medicine and formulation science, and the deep understanding of lung function and pulmonary diseases such as asthma and chronic obstructive pulmonary disease, it has been recognized that pulmonary administration is the best mode of administration for pulmonary diseases. The inhalation therapy can directly act on the lung, has high local drug concentration, quicker response and better curative effect, and can avoid or reduce the side effect possibly generated by systemic medication.

The existing atomizer has a lot of inconvenience in use. On the one hand, frequent aerosol inhalation treatment, if the atomizing screen piece is not cleaned in time and easily causes blockage, the atomizing efficiency of the atomizer is influenced, and the atomizing particle size is also influenced, so that the effective inhaled quantity of the medicine can be reduced as a final result. On the other hand, if the atomization screen sheet is not completely dried after cleaning, bacteria are easily grown. Moreover, when the medicine needs to be atomized for a long time to maintain the treatment, the atomizing screen can greatly shorten the service life of the atomizer through multiple frequency use, reduce the accessibility of the medicine and increase the cost of patients.
